Skill UI

This expert specializes in secure mobile development practices, covering areas like input validation, WebView security, secure data storage (KeyStore/Keychain), and advanced network security (Certificate Pinning). Use this skill to write secure, resilient mobile code for both iOS and Android, mitigating platform-specific vulnerabilities and ensuring sensitive data protection.

A comprehensive guide covering the entire lifecycle of building VS Code extensions, from initial scaffolding to successful Marketplace publication. Learn best practices for Webviews, TreeViews, testing, packaging, and troubleshooting, ensuring compatibility with the latest APIs.

A comprehensive playbook for expert-level Android application security testing. It covers advanced exploitation techniques, including SSL pinning bypass (using Frida/Objection), detecting component exposure (activities, providers, services), and exploiting WebView vulnerabilities (RCE, XSS). Essential for authorized mobile penetration testing assessments.

Utilizes Expo DOM components to render web code verbatim inside a webview on native platforms, while maintaining native rendering on the web. This enables developers to integrate web-only libraries (such as charting tools, syntax highlighters, or complex CSS layouts) and incrementally migrate existing web components into a React Native application without substantial rewriting.

A specialized skill for advanced runtime analysis of Android applications, primarily used in CTF and security research. It covers techniques like hooking specific system boundaries (JNI, WebView), bypassing security measures (SSL pinning, root checks), and recovering sensitive data or request signatures. Ideal for deep inspection of app trust boundaries and complex mobile logic.

A comprehensive guide for developing full-featured VS Code extensions from scratch or converting existing web applications (JS/React/Vue). Learn to implement custom commands, complex webviews, hierarchical tree views, custom editors, and integrate advanced features like AI agents using file-bridge IPC. Supports modern build stacks including TypeScript, esbuild, and Vite.

This skill specializes in secure mobile application development, focusing on input validation, WebView security, and mobile-specific security patterns. It covers secure data storage, authentication implementation, and platform-specific vulnerabilities for iOS and Android. Ideal for building security-first mobile apps that protect sensitive data against common attack vectors like injection and man-in-the-middle attacks.

Expo DOM components allow running web code directly in native webviews, enabling the use of web-only libraries like Recharts without modification. This facilitates incremental migration of web code to native apps and supports complex HTML/CSS layouts not available in standard React Native.
